India sharpening stones are used for coarse sharpening knives on KME or Hapstone knife sharpeners. India is one of the oldest and the most well-known sharpening stones in the USA. India stones are made of oil-treated aluminum oxide. All India stones are 5-6 mm thick.
It is advisable to use India stones to sharpen knives made of soft or medium stainless steel. Use of India stones to sharpen knives made of hard steel is not recommended – use Crystolon instead.
India Stones may be used with oil as a lubricant, or without lubricants at all.
